A Stockholm detective under internal investigation heads to a ski resort to unwind, until a young girl's disappearance compels her back to work.

Police officer Hanna Ahlander has been suspended from her job in Stockholm and dumped by her partner when she moves to her sister's vacation home in Åre. When a young woman goes missing on the icy night of Lucia, Hanna can't help but start investigating the case. With a tough family situation and an understaffed police station, local police officer Daniel Lindskog reluctantly has to accept Hanna's help. But the big question is whether they can trust each other.
